whatever that "grass" is it comes up in winter, and it's dammed hard to kill. Fortunately, its easy to pull. I always get some of it in my yard. Treating with pre-emergent in the fall seems to take care of most of it.

Sounds like the grass you are speaking of is annual blue grass, all I can say is pull it before it seeds or you will be spraying MSMA on it this spring. Get a close up pic of the grass
